Abstract

It is now fairly understood how speech articulation and recognition are modified under cognitive stress situations as those produced when the process of HMI (Human Machine Interfacing) takes place while performing a cognitively demanding task, very likely to be produced in a GCS (Ground Control Station). Cognitive sciences have provided a solid background for these phenomena. However, there is a lack of ASR (Automatic Speech Recognition) systems capable of adapting to these kinds of situations for several reasons: first, the absence of robust multimodal cognitive stress detection methods, second, the need to develop computational models for those phenomena and third, the necessity of flexible acoustic models with the plasticity enough to fully assume their wealthiness. We believe that a close resemblance of these phenomena described by cognitivists and the detection of the acoustic cues together with the employment of advanced acoustic models can lead to a stress aware and adaptable ASR system suitable for GCS.

SAVIER is a macro-project that integrates 12 research lines to develop in an integrated way human-machine interfacing technologies for unmanned aerial vehicles’ systems including mission planning, situational-awareness, operators’ stress management and decision support.
